Which organization specifically works on improving international standards of aviation safety?

The International Civil Aviation Organization (ICAO) is the organization specifically responsible for improving international standards of aviation safety. Established in 1944, ICAO works to develop global aviation safety standards and practices, which member states implement in their national regulations. One of its key roles is to promote the safe and orderly growth of international civil aviation through cooperation among its 193 member states. This includes setting standards and recommended practices in various areas such as aircraft operations, air traffic management, and aviation security.

ICAO also conducts audits and safety assessments to monitor adherence to these standards, providing a framework that ensures a high level of safety in international air travel. In contrast, other organizations listed have different focuses: the Federal Aviation Administration (FAA) primarily oversees aviation safety within the United States; NASA is focused on space exploration and aeronautical research; and the International Air Transport Association (IATA) represents airline interests but is more centered around improving airline operational efficiency and passenger experience rather than setting safety standards.
